Snake fights against the impostor.

A decoy posing as FOXHOUND spy John Turner was active on an enemy base during Operation 747, in an attempt to lure Lt. Solid Snake into a trap. When the operation started, Turner let himself be captured by enemy soldiers, in order to ensure Snake's successful infiltration. After that, a rumor spread claiming that Turner was locked up in a train heading towards the main complex of the base. Snake infiltrated the train to save him, guided by Turner via transceiver, though the latter falsely said there were no traps or enemies along the way. When Snake finally reached Turner, it was revealed that he was just a body double. The two fought, and Snake successfully killed the impostor.

The real John Turner was reported as missing in action after the mission's completion.
